We look at the division of 72312698 by 830 
The aim is to understand the frequency of 830 in 72312698.

Let's proceed to step 1:
The number 830 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 830

Advancing to step 2:
830 goes into 72 0 times with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Bring next digit (3) of the dividend behind the 72 and repeat the process: 723 / 830

Advancing to step 3:
The number 830 fits into 723 0 times, leaving a remainder of 723.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 723, we get 723.
Bring next digit (1) of the dividend behind the 723 and repeat the process: 7231 / 830

Going ahead to step 4:
830 goes into 7231 8 times with a remainder of 591.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 6640 from 7231 to get 591.
Bring next digit (2) of the dividend behind the 591 and repeat the process: 5912 / 830

Advancing to step 5:
5912 divided by 830 is 7 with a remainder of 102.
Write down 7 as next digit of the result. 
Result so far: 87.0
Subtracting 5810 from 5912 leaves us with 102.
Include the next digit (6) from the dividend after 102, then repeat: 1026 / 830

On to step 6:
1026 divided by 830 is 1 with a remainder of 196.
Record the quotient 1 as the next digit in the result. 
Result so far: 871.0
Subtract 830 from 1026 to get 196.
Bring next digit (9) of the dividend behind the 196 and repeat the process: 1969 / 830

Let's proceed to step 7:
830 can be fit into 1969 2 times, resulting in a remainder of 309.
Put 2 as the next digit of the answer. 
Result so far: 8712.0
If we take 1660 away from 1969, we end up with 309.
Include the next digit (8) from the dividend after 309, then repeat: 3098 / 830

On to step 8:
If we divide 3098 by 830, we get 3 and a remainder of 608.
Put 3 as the next digit of the answer. 
Result so far: 87123.0
The remainder is 608 after subtracting 2490 from 3098.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Going ahead to step 9:
The number 830 fits into 6080 7 times, leaving a remainder of 270.
The next digit of our result is 7. 
Result so far: 87123.7
Deduct 5810 from 6080 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 10:
830 can be fit into 2700 3 times, resulting in a remainder of 210.
Record the quotient 3 as the next digit in the result. 
Result so far: 87123.73
If we subtract 2490 from 2700, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 11:
The number 830 fits into 2100 2 times, leaving a remainder of 440.
The next digit of our result is 2. 
Result so far: 87123.732
Subtracting 1660 from 2100 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 12:
When dividing 4400 by 830, we get 5 with a remainder of 250.
The next digit of our result is 5. 
Result so far: 87123.7325
If we take 4150 away from 4400, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 13:
830 goes into 2500 3 times with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 87123.73253
If we subtract 2490 from 2500, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
If we divide 100 by 830, we get 0 and a remainder of 100.
The next digit of our result is 0. 
Result so far: 87123.73253
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 15:
If we divide 1000 by 830, we get 1 and a remainder of 170.
The next digit of our result is 1. 
Result so far: 87123.7325301
The remainder is 170 after subtracting 830 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 16:
The number 830 fits into 1700 2 times, leaving a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 87123.73253012
Subtract 1660 from 1700 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 87123.73253012 with a balance of 4e-08.
